If the circles circumference is 90% of another circles then the ratio would be 10:9, Circle A would be 10 and Circle be would be 9
The is a subtraction equation, so the smaller number from the bigger number.
1743 - 576 = 1167 :3
Answer:
Step-by-step explanation:
Arc length of the circle is given by,
Arc length = 
Area of the sector of a circle = 
22). Arc length of the circle having central angle = 
= 60°
Arc length = 
= 
= 7.33 cm
23). Arc length of the circle having central angle = 225°
Arc length = 
= 12.5π
= 39.27 km
24). Central angle = 
= 
= 225°
Area of the sector = 
= 43.20 yd²
25). Area of the sector = 
= 65.97 yd²
